A ruby method that takes a block and calls that block

In an application of mine, I have some code that looks like this:

if is_translation?
  @booking.enable_dirty_associations do                                           
    booking_update
  end
else
  booking_update
end

I would like it instead to look like this:

is_translation? ? @booking.enable_dirty_associations : func do
  booking_update
end

Where func is the method that takes the block and just executes it.

Is there a built in Ruby method, or perhaps a combinator function that does this?

It would be pretty easy to write func() for yourself:

def func
  yield
end

Unfortunately, however, your idea won't work, the block will only apply to func, not the first call. The only way I can think of to get close to what you want is to define the block as a proc and pass it manually:

block = Proc.new { booking_update }

is_translation? ? @booking.enable_dirty_associations(&block) : block.call

This does have the advantage of not needing the func() method.
